CARLETON ELLIS, OF WHITE PLAINS, NEW YORK, ASSIGNOR TO CHADELOID CHEMICAL COMPANY, OF NEW YORK, N. Y., A CORPORATION OF WEST VIRGINIA.

PAINT OR VARNISH REMOVER AND THE PREPARATION TITEREOF.

No Drawing.

To all whom it may concern:

Be it known that I, CARLE'ION ELLIs,'of White Plains, in the county of Westchester and State of New York, have made certain new and useful Inventions Relating to Paint or Varnish Removers and the Preparation Thereof, of which the following is a specification.

This invention relates to paint or varnish removers and the process of making the same and relates especially to removers of a generally ketonic character especially desirable for the removal of shellac and other varnish coatings.

In the manufacture of acetone, calcium acetate is generally employed as a raw material and the commercial processes produce a considerable proportion of oily body as well as the acetone desired. This oily material may be separated from the acetone by agitation with water which absorbs the acetone and similar water-soluble ketones, leaving the other materials in a separated condition. This residual oily material comprises pinacolins and condensation products of the higher ketones. This material may be deodorized, that is, deprived of its disagreeable odor to a considerable extent when used for removers by treatment with metallic sodium or similar material which seems to combine with these substances to form polymeric bodies which are solid at ordinary temperatures and which may be more readily separated from the liquid components by distillation. Metallic sodium also seems to reduce certain unsaturated compounds by virtue of the nascent hydrogen which is liberated when the metal comes in contact with these organic bodies. The saturated bodies resulting have very much less odor than the unsaturated bodies from which they are formed. After this deodorizing process and distillation of the treated material the ketonic condensation products comprising pinacolins and allied bodies may be used in preparing paint or varnish removers either alone or in conjunction with other alcoholic or ketonic bodies and in connection with benzol, its homologues or other wax solvents, it being understood, of course, that stiffening materials, such as wax, wood flour, whiting, infusorial earth and the like may also be used to increase the consistency of the compound.

Aiiillustrative remover of this character Specification of Letters Patent.

Patentefl Oct. 20, 191 4.

Application filed February 18, 1907. Serial No. 858,101.

may be prepared according to the following formula: Higher ketonio condensation products, preferably deodorized as indicated, 10

parts, chlor benzol 5 parts, benzol 3 parts,

light kerosene 2 parts, ceresin wax or siniilar waxy bodies, 1' part, wood flour 7 "parts. Another illustrative remover of this character may contain higher ketonic condensation products, such as the pinacolins derived from acetone as described, 12 parts, benzol 3 parts, ceresin wax 1 part. Still another illustrative remover wh ch may be used, if

desired, for dipping or tank work may contain higher ketone condensation products 15 parts, kerosene, about 120, 6 parts, paraffin 'wax, if desired, part. -derstood that the proportions of the stiffening material may be varied considerably ac- It is, of course, un-v cording to the class of work in which the remover 18 to be used, and it is not necessary in all cases to use the wax or other stiffening material. Furthermore, the benzol and other wax solvent ingredients may in some, cases be omitted, for instance, where the remover is intended solely for use on varnish coatings. v

This invention has been described in connection with a number of illustrative ingredients, formulas, proportions and proc esses, to the details of which disclosure the invention is not, of course, to be limited.
